.SH "NAME"
Image::ExifTool::Geotag \- Geotagging utility routines
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
This module is used by Image::ExifTool
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This module loads \s-1GPS\s0 track logs, interpolates to determine position based
on time, and sets new \s-1GPS\s0 values for geotagging images.  Currently supported
formats are \s-1GPX, NMEA RMC/GGA/GLL, KML, IGC,\s0 Garmin \s-1XML\s0 and \s-1TCX,\s0 Magellan
\&\s-1PMGNTRK,\s0 Honeywell \s-1PTNTHPR,\s0 and Winplus Beacon text files.
.PP
Methods in this module should not be called directly.  Instead, the Geotag
feature is accessed by writing the values of the ExifTool Geotag, Geosync
and Geotime tags (see the Extra Tags
in the tag name documentation).
.SH "NOTES"
.IX Header "NOTES"
To take advantage of attitude information in the \s-1PTNTHPR NMEA\s0 sentence, two
user-defined tags, GPSPitch and GPSRoll, must be active.
